Oxidation sites for plasmon-induced charge separation at gold nanocubes and nanorods on TiO₂ were visualized by PbO₂ deposition, and the sites were localized at plasmonic resonance sites. This indicates that energetic holes generated at those sites dominate the reactions, which can be applied to photo-nanofabrication beyond the diffraction limit.
